Ubuntu 12.04:

root at vms3:~# l /proc/self/ns/mnt
l: /proc/self/ns/mnt - No such file or directory

root at vms3:~# uname -a
Linux vms3 3.2.0-55-generic #85-Ubuntu SMP Wed Oct 2 12:29:27 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

What is "new enough"?

So, from the host system, a remount is not possible?
